The patient inquires about how his body will kill pathogens unassisted by antibiotics.
The nurse responds that a process called phagocytosis will:
Stimulate the production of interferons.
Engulf and destroy the pathogen.
Create antibodies against the pathogen.
Stimulate the body to make more white blood cells.
The Correct Answer is B
Choice A rationale
Interferons are proteins produced by cells in response to viral infections and are part of the body's immune response, but they are not directly involved in the engulfing of pathogens.
Choice B rationale
Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and destroy pathogens. This is a crucial mechanism of the innate immune system.
Choice C rationale
Creating antibodies is the function of B cells in the adaptive immune system, which works alongside phagocytosis but is not the same process.
Choice D rationale
Phagocytosis itself does not stimulate the body to make more white blood cells, but it is a function performed by existing white blood cells to eliminate pathogens.

Correct Answer is D
Explanation
Choice A rationale
Gloves are often the most contaminated piece of PPE. They should be removed first to prevent contamination of other PPE or areas.
Choice B rationale
The gown should be removed after gloves because it covers the largest surface area and could spread contaminants if removed earlier.
Choice C rationale
Eyewear should be removed before the mask to avoid potential contamination from airborne particles that could remain on the mask.
Choice D rationale
The mask is typically removed last to prevent inhalation of any contaminants that might still be in the air during the removal process.
Correct Answer is C
Explanation
Choice A rationale
Symptoms of an infection may not always appear within 48 hours. The incubation period varies depending on the infectious agent and can range from hours to weeks, during which the person may not show any signs of illness.
Choice B rationale
A person in the incubation period does not exhibit symptoms and, therefore, is unlikely to seek medical attention for symptom relief. Medical attention is usually sought when symptoms manifest and impact the person's well-being.
Choice C rationale
During the incubation period, the person can transmit the disease to others even if they do not feel ill. This period involves the replication of the pathogen within the host, and the person may be contagious without knowing it.
Choice D rationale
Identifiable signs of a specific illness appear during the symptomatic phase, not during the incubation period. The incubation period is the time between exposure to the pathogen and the appearance of initial symptoms.
